Can A Body Have A Constant Velocity And Still Have A Varying Speed? No, a body
can not have its
velocity constant, while its speed varies. Rather, it can have its speed constant and its velocity varying. For example in a uniform circular motion.
Can a body have constant velocity but still a varying acceleration?
Since speed is equal to the magnitude of the velocity vector, it will also be constant. Again, since the acceleration is the rate of change of velocity of a body with time, if the velocity is constant, the acceleration of the body will be zero. … Hence,
a body can have a constant speed
and still be accelerating.
Can the velocity of a particle reverse in direction when the acceleration is constant explain?
Yes
. Direction of velocity of an object can be reversed when it’s acceleration is constant. … After reaching highest point, its direction will be reversed while its acceleration will remain same i.e. due to gravity.
Can acceleration be non zero when velocity is zero?
It is possible to have a
non-zero
value of acceleration when the velocity of a body is zero. … At the point where the velocity becomes zero, only the instantaneous velocity of the body is zero, at any time before or after this time, the object has a non-zero velocity.
Can an object subjected to a constant acceleration reverse its velocity?
Can an object reverse its direction of travel while manning a constant acceleration? …
Yes it is possible for an object to maintain constant acceleration
and change direction as in case of a free fall object which goes up and down changes its direction but its acceleration remains the same.
Can a body have zero velocity but finite acceleration?
In the simple harmonic motion during the motion, at the extreme positions, the velocity of the body is zero but the acceleration is highest. … Therefore, a body can have zero velocity and
finite acceleration
.
When velocity is 0 What is acceleration?
At the highest point, the velocity of the ball becomes zero, after which it starts to fall down. At this point, the velocity of the ball is zero yet its acceleration is equal to
g=9.8m/s2
.
Why retardation is called negative acceleration?
The change in velocity of the object is zero. Hence, the object at rest or in uniform motion has zero acceleration. …
If the velocity of the object decreases then the object is said to have
a negative acceleration and the meaning of retardation is decreased. Therefore, retardation means negative acceleration.
Can an object’s velocity change direction when its acceleration is constant group of answer choices?
Yes
, an object’s velocity can change direction when its acceleration is constant.
Can a body have acceleration when it is at rest?
Yes
, acceleration is a change in velocity, so an object might be momentarily at rest but a split-second later have some speed, i.e. it can be changing its velocity even if it is momentarily at rest. An example is a vertically thrown ball at the top of its trajectory, or a yo-yo just as it turns around.
Can a body have zero velocity and finite acceleration Class 11?
Yes
, a body can have zero velocity but finite acceleration.
Why a body having uniform velocity has zero acceleration?
It measures how much velocity is changing in a given time interval. If the body has uniform velocity, it means
velocity is not changing
. So the change in velocity is zero. In other words, its acceleration is zero.
Can a body have zero velocity and finite acceleration along a straight line motion give example?
In the simple harmonic motion during the motion, at the extreme positions, the velocity of the body is zero but the acceleration is highest. for example,
the simple harmonic motion of spring and the simple harmonic motion of Pendulum
. Therefore, a body can have zero velocity and finite acceleration.
Can there be acceleration without velocity?
Answer:
Yes
, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction.
When velocity is maximum What is acceleration?
So, when velocity is maximum, acceleration is
minimum (zero)
.
How do you know if acceleration is 0?
When acceleration is zero (that is, a = dv/dt = 0),
rate of change of velocity is zero
. That is, acceleration is zero when the velocity of the object is constant. Motion graphs
